Postminimalism is an art movement that emerged in the late 1960s as a reaction to the strict formalism of Minimalism. While Minimalism focused on simplicity and the use of industrial materials, Postminimalism embraced a more expressive and varied approach. Artists began to incorporate personal narratives, organic forms, and a wider range of materials, often blurring the lines between art and everyday life. Key figures in Postminimalism include Eva Hesse and Robert Morris, who explored themes of process and the physicality of materials. This movement allowed for greater emotional depth and complexity, encouraging artists to engage with their work on a more personal level, thus expanding the definition of contemporary art.
